Yes. The US is already increasing exports from the Gulf and UAE broke with OPEC to increase the throughput of Fujairah. If Gulf countries start exporting through Fujairah or other ports, it's eventually game over for Iran.
It’s probably still a lot cheaper to pay toll than moving cargo from Jebel Ali to Fujairah over land
All of those are within range of Iranian missiles and drones. The only ways out of this are total war or final settlement giving Iranian favorable terms.
